Kardio is a simple tool that can be configured to perform health checks on any endpoint. Kardio has a rich UI showing status and availability based on responses from REST endpoints, TCP ports, etc. It is also integrated with Slack and email for alerting.

Polaris helps keep your cluster healthy. It runs a variety of checks to ensure that Kubernetes deployments are configured using best practices that will avoid potential problems in the future. The project includes two primary components:

A dashboard that provides an overview of how well current deployments are configured within a cluster.
An experimental validating webhook that can prevent any future deployments that do not live up to a configured standard.

Alertmanager UI is useful for browsing alerts and managing silences, but it's lacking as a dashboard tool - karma aims to fill this gap. Starting with 0.7.0 release it can also aggregate alerts from multiple Alertmanager instances, running either in HA mode or separate. Duplicated alerts are deduplicated so only unique alerts are displayed. Each alert is tagged with names of all Alertmanager instances it was found at and can be filtered based on those tags (@alertmanager). Note that @alertmanager tags will be visible only if karma is configured with multiple Alertmanager instances.

Cyclotron is a platform for creating and hosting dashboards, independent of any single data source. It's a batteries-included solution for loading and visualizing data without programming. It's the CMS of dashboarding.
